US 2008/0176169 A1 · BINDER COMPOSITION AND PHOTOSENSITIVE COMPOSITION INCLUDING THE SAME

Abstract

The present invention relates a binder composition and a photosensitive composition including the binder composition. In one embodiment, a binder composition includes a copolymer of monomer M1, M2, M3 and M4, wherein the monomer M1 can be represented by the following formula: the monomers M2, M3 and M4 can be represented by the following formula, however the monomers M2, M3 and M4 are different from each other, wherein R1, R2, R3 can be selected from the group consisting of hydrogen and alkyl group, R4 is an aromatic group, R5 can be selected from the group consisting of hydrogen, aromatic groups, alkyl groups, substituted alkyl groups and alkyl groups interrupted by an oxygen atom. The copolymer has good developing ability and a black matrices made therefrom has good mechanical properties.
